Jets and Magnetic Fields
In this paper we examine some key results to date on the properties of jets from relativistically compact objects. The approach is historical because in a confused theoretical situation it is useful to evaluate results on the basis of their frequency of recurrence. Some important results are isolated but a comprehensive review is not attempted. The various categories of theory associated with jets from non-relativistically compact objects are surveyed in the same way. It is claimed that one simple set of (nearly) dimensional relations goes a long way! There is much repetition in this area. Finally some new work on the magnetic two-point correlation functions is briefly reported. We believe that such a stochastic approach is preferable to the usual semi-deterministic dynamo theory.
